TriMet went into the afternoon commute Friday with buses on chains, MAX lines running on regular routes and TriMet crews working to keep the system running, according to Roberta Altstadt, spokeswoman for the transit agency.

“We thank our riders for their understanding as we all weather this storm,” Alstadt said. “We continue to encourage folks to bundle up and be prepared for delays. Also check before you go at trimet.org/alerts.”

About 3:45 p.m., she said MAX trains are running on about 20- to 30-minute frequency and that crews were working to get the Sunset Transit Center and Northeast 60th Avenue MAX Station elevators working.

As for buses, Alstadt said they were doing “relatively well. They are running on chains so they cannot go more than 25 miles per hour.”

She said that buses are running slow but on fairly consistent intervals. She said that while most lines are on their regular routes, TriMet has had to cancel about seven routes and put detours on about 18 others. TriMet normally has 79 routes, total.

Most of our bus lines are running on regular route. We do have about 7 lines canceled and about 18 others on snow route or detoured.

As for WES Commuter Rail, Alstadt said it “has been handling the storm rather smoothly and we expect that to continue for this evening’s commute.”
